[Solved] surfaceExtractors and pointer

zprg · **Posted:** Thu May 09, 2013 7:17 am

if i use a pointer to a SimpleVolume it compiles and works for example then i have to write
maxx=volpointer->getWidth();
if i then use a pointer to a SurfaceExtractor from the Volumepointer(the same with Normals or Marchingcubes)

Code:

PolyVox::MarchingCubesSurfaceExtractor <PolyVox::SimpleVolume<MDVoxel>>*  surfaceExtractorMCPointer;
PolyVox::MarchingCubesSurfaceExtractor <PolyVox::SimpleVolume<MDVoxel> >  surfaceExtractorMC(volpointer, volpointer->getEnclosingRegion(), &polyvoxmesh);
surfaceExtractorMCPointer=&surfaceExtractorMC;
surfaceExtractorMCPointer->execute();

the program also compiles but the program hangs up, please whats wrong cause it compiles it seems to be correct c++

Are you sure it it the use of a pointer which is the problem here? That seems unlikely. So just to be clear, you say that this code will work:

Code:

surfaceExtractorMC.execute();

But that this code will crash:

Code:

surfaceExtractorMCPointer=&surfaceExtractorMC;
surfaceExtractorMCPointer->execute();

Seems very strange... If that's not what you mean, then can you give an example of working code compared to non-working code?
